@owend Is it possible to do this on RepRap 3.1.x, before the addition of events in RepRap 3.4?

I have an application that needs to do some further processing with the details of heater faults, but I can’t find where that information is stored outside of the message shown on the Duet web control. For example, if the heater faults because the temperature rises too slowly or too quickly, I need to know that information. How can I get that information outside of the web control?
